'Applicatiqn fuea separaterl 3, i919. serial No. 321,387.

To all whom t may concern.'

j Be it known that we', FRANK and WILLIAM N. MARSDEN, citizens ofthe United States, residing at Amsterdam, in the county of Montgomery and State of'New York, have invented new and useful lImjnfoven'lents in Adherently Uniting Webs of a specification.

Reference may be had to the accompanying drawings, and the reference characters marked thereon, which form a part of this specification. Similar' characters refer to similar parts in the several figures therein.

In the manufacture of certain articles from a plurality of thicknesses of fabric it is necessary that the thicknesses or plies of fabric should be adherently united sothat during the manufacture of the article the' pluralityof plies act and are treated in 'substantially the same manner as a singleply fabric.

j Where the fabrics are of a delicate texture, much difficultyr is experienced. in thus adherently uniting a plurality of webs'or plies, due to the tendency of the adhesive toform substantial areas of hardened adhesive at more or less frequentintervals between the plies, and also to the tendency of thejad- .hesive to permeate the fabrics so as to render its presence apparent by discoloration or other injurious 'effectupon the outer surface of the fabrics.

In the manufacture of silk -and cotton gloves it is customary to employ a plurality of adherently united plies` usually two, of silk or .cotton fabrics which are quite thin and of fine texture; and it is found difiicult inv adherently uniting plies of such fabrics to avoid visible evidence of the adhesive on the outer surfaces of the plies, as well as to J. KAUFLMNN substantially uniform flexibility throughout the adherenjtly united plies; and to prevent visible evidence ofthe adhesive on the outer surfaces lof the plies. i

f )ther objects will appear in connection with the following description.

v In carrying` out our invention we adherently unite the plies or webs by pressing them together after having interposed between nei-ghboring surfaces thereof an adhesive substance accompanied by moisturev .ln'such limited quantities as to cause fibres of one web to adhere directly to substantially opposite 'fibres of the other web independently of the surrounding fibres in said webs, as a result of which the fabrics are adherently united'directly together at a multitude of points each independent of the other points, so that the compound fabric thus formed is substantially as'fleXible as though no adhesive were present.

Fig. l of the drawings is a view inside elevation of a machine for adherently uniting two webs or plies'of fabric in accordance with our invention, with thedriving connec- Itions betweenthe main-power-shaft and the 4by their respective nozzles are moved through arcuate paths. j

Fig. 5 is a vertical cross section taken on the broken line 5 5 in Figs. 2 and 4, showing in elevation certain parts of the mechanisms whereby the reciprocating movements of the distributing devices for the powder and moisture are accomplished.

Fig. 6 is a view in side elevation on a larger scale of a broken-away portion of the same, including the clutch-mechanism shown in Fig. 5.

Fig. 7 is a top plan view of the clutch-disk shown in Fig. 6.

Fig. 8 is a top plan view of a set of circumferentially grooved rollers between which the adherently united webs are passed before they are wound up into a roll.

Fig. 9 is a view in elevation of the same. Fig. 10 is a horizontal cross-section taken on the broken line 10-10 in Fig. 5, viewed from above.

Fig. 11 is a vertical cross-sectionof the same taken on the broken line 11-11 in Fig. 10.

Fig. 12 is a vertical longitudinal section able along open slideways formed in the bracket-s, 2, whereby said' roll, 4, can be ad-i `justably moved toward and from the roll,

3. This adjustment by movement of the roll,

4, is accomplished by means of a screw, 6,

actuated' by a hand-wheel, 7, in the usual` manner. I

The rolls, 3 and 4, may be made of -any desired material, but we prefer to make the. roll, 3, of polished iron and the roll, 4, of rubber. These rolls, 3 and 4, are adapted to press together-an "upper web, 8, and a lower web, 9, of fabric which webs L are to be adherently united.

The web, 8, is fed from a roll, 10, and the web, 9, from a roll, 11, said rolls being rotatively mounted upon .bearings on the frame of the machine, the bearings for the roll, 10, being formed in an upright bracket, 12. A

A tension .device is provided for each of said rolls, the same consisting of a round strap,- 13, which'passes around a grooved'- pulley, 14, in fixed relation to the respective roll, the ends of said strap being connected by a coil-spring, 15, and an adjustable screw take-up, 16, with'a lug, 17, in xed relation to the frame of the machine.

In passing from the rolls 10 and 11, tothe rolls, 3 and 4, the respect-ive webs pass aroundseparate spreading-rolls, 18 and 19, whereby the respective webs are stretched transversely to compensate for the natural.

contraction of the fabric transversely as the webs leave the'supply-rolls, 10 and 11.

Each spreading-roll has upon its surface two ribs, 20 and 2l, which Wind spirally The pitch of the spiral ribs, 20 and 21, isl

in such a direction that as the web passes around the ribbed roll the spiral ribs exert a worm-like action upon the web from the center toward the side edges of the web, thus tending to spread or stretch the web trans? versely.

rlhe two webs, 8 and 9, after' passing between the rolls, 3 and 4, pass around a drum,

23, rot-atively mounted in bearings on they frame of the machine and rotated by suitable driving-connections with the main power-shaft, 22.y

This drum, 23, is preferable heated in some suitable manner as by steam; and it preferably has a smooth metal surface.

At substantially the point where the combined webs first make contact with the drum,`

23, they are pressed against the drum by means of a padded roll, 24, which may be an idle roll and which is shown mounted in bearings in the oscillatory ends of links, 25, pivoted at\26, upon the frame of the machine,- which links extend obliquely upward and rearward whereby said roll, 24, rests by gravity against the drum, 23.

he drum-encircling-webs after leaving the roll, 24, are moved past a fan, 27, rotatively mounted in bearings on the frame of the machine, and driven by suitable connections with the main power-shaft.

The webs pass from the drum, 23, after approximately encircling the drum, over a roll, 28, rotatively mounted in bearings formed in upright brackets, 29, mounted on the frame of the machine from which roll, 28, the webs pass between two successive pairs of loosely interengaging circumferentially grooved rolls, 30, whichV .impart to the webs'a sinuous form in cross section corresponding to theform of the space between ach pair of said grooved rolls, as shown in From the grooved rolls, 30, the webs pass/ between a pair of padded rolls, 31, whereby the webs are restored to flattened condition. The webs then pass to` a take-up roll, 32, adapted to rest upon a driving roller, 33, the roller, 33, being driven by a step-by-step movement by means of pawl-and-ratchet mechanism, 34, the reciprocating member of which is actuated'by means of suitable connections with the main power-shaft.

'The trunnions of the take-up'roll, 32, are mounted in vertical slideway grooves, 35, in upright brackets, BGNrGCted from the frame of the machine,

By removing the screw-bolts, 40, the

upper set of said rolls can be' swung upwardly away from-the lower set of rolls to facilitate the insertion of the webs between the upper and lower rolls. i y

At the front end of the machine -we provide means for interposing between the. neighboring surfaces of the webs, 8 and 9,`

adhesive material such that in the subse quent o eration of the machine, the two webswi l be adherently united.

For certain purposes of the invention the means for so interposing the adhesive mate- I rial may be of any known form, and the adhesive material may be applied to the webs in any known manner.

We have shown in the drawings a preferred form of means for thus applying adhesive to the webs whereby a supply of adhesive powder is carried by an air-blast `into the angle between the two webs in advance of the rolls, 3 and 4, while at the same time. a supply of atomized water is also blown into said angle sufficient to develop the' adhesive properties of the adhesive powder.

A supply of adhesive powder is carried by a container, 41', which is rotatively mounted upon a bracket, 42, which is clamped upon a cross-rod, 43, ixedly secured in the upper ends of a pair of uprightv brackets, 44,.erected from the frame of the machine.

Air under pressure is admitted to the base, 45, ofthe container, 41, whereby the powder is blown from the container in a y blast through the nozzle, 46. By oscillating movement of the container, 41, and its nozzle, 46, the nozzle is reciprocated through an arcuate path'whereby the adhesive powder is distributed transversely of the webs.

A water-supply tank, 47, is mounted upon the lower end of a bracket, 48, which bracket is clamped' i upon the cross-rod, 43; and rotatively mounted upon the water-tank, 47, is a post, 49, connected at its upper end with an air-supply pipe, 50, by means of a cou pling at 51, which permits oscillating movement ofthe post, 49,

The upper end` of the post is provided with an air-passageway, 52, connecting with the assagewayy through the pipe, 50.

' T e lower end'of the post is'V provided with a passageway, '53, leading from the water-tank, 47, with a nozzle-opening, 454,-

opening laterally through the side of the post.

An lexternal air-pipe, 55leads from the lower end of the air-passageway, 52,through the front of the post at a point opposite the nozzle-opening, 54 whereby compressed air supplied from the pipe, 50, is forced through the nozzle-opening, 54, carrying with it in atomized form 'a supply of water from the y water-tank,-47. '75

By oscillating the post, 49, this supply of atomized water is distributed throughout the width of the webs to develop the adhesive qualities of the powder distributed by the nozzle, 46.

Oscillating movements are imparted to the powder-distributing nozzle, 46, and the water-distributing nozzle, 54, in opposite directions by means of a toothed-rack, 56, which is adapted to reciprocate through slideways, 57, on the bracket', 48, in engagement with a gear-segment, 58, fixed upon the powder-container, 41, anda gear-segment, 59, fixed upon the base of the post, 49.

Reciprocating movements are imparted to the toothed-rack, 56, by means of a pitmany connection', 60, between said rack and a crank, 61, fixed upon the upper end of a vertical shaft, 62, rotatively mounted in bearingson a bracket, 63fixed upon the frame of the machine.

A slot` 77, in the rack, 96, provides lost- -motion in its connection with the pitman,

A mains at rest for a brief interval at the beginning and end of each movement in' each direction.

The shaft, 6 2, is rotated by means of a beveled .gear-connection, 64, between said shaft and a shaft, 65, carrying a sprocketwheel, 66, which is driven by means of suitable connections with the main power-shaft of the' machine.

rThe shaft, 62, is divided, its upper and lower ends being operatively connected to-` gether by means of a clutch-member, 67, slidably mounted upon the lower member of the shaft, and provided with slots, 68, sever-A ally adapted to receive a pin, 69, on the upper member of the shaft when the clutchmember, 67. is forced upward by means of, the coil-spring, 7 0, which encircles the lower member of said shaft. y

The clutch-member isy adapted to be dislengaged by means of a lever, 71, fulcrumed The arrangement of the cam, 74, is such that when the supply of compressed air is cut off by the valve, 75, the clutch-member, 67, is disengaged from the pin, 69, and vwhen the Valve is open the clutch-member, 67, is in engagement with the pin, 69, causing the powder-distributing nozzle, 46, and the water-distributing nozzle, 54, to be oscillated whenever they are being supplied with compressed air.

A preferred -form of powder-distributing apparatus adapted for use in the above described machine is shown and described in an application filed by Frank J. Kaufmann, October 9, 1918, Serial No. 257,498, for powder-distributors.

The operation ofthe machine is as follows:

As the webs, 8. and 9, pass from their respective rolls to the worm-rolls, 18 and 19, a blast of adhesive powder is blown from the nozzle, 46, into the angle between said webs upon neighboring surfaces of which webs the powder is deposited. At the same time a supply of atomized water is blown from the nozzle-opening, 54, into said angle, and the atomized moisture thus deposited upon these neighboring surfaces ofl the webs develops the adhesive qualities of the adhesive powder, causing the resultant adhesive to adherently unite the webs as they pass between the rolls, 3 and 4. y

As the united webs pass around the drum, 23, they are further pressed together and against the heated drum by the roll, 24, while subjected "to the blast from the fan, 27. As the united webs pass around theheated drum, 23, they become thoroughly dried, and leaving the drum, 23,.they pass around the roll, 28, and thence to the grooved-rolls, 30. shield, 76, interposed between' the stretch of the webs between the rolls, 28, and the grooved-rolls, 30, and the' stretch of the webs which is on the upper side of the drum, 23, serves to protect the upper stretch of the webs from any steam or moisture which might emanate from'the webs in their passagearound the heated drum.

ln passing between the grooved-rolls, 30, the united webs are flexedand bentin 'different directions whereby should there be any substantial area of hardened adhesive between the webs it will be broken up to render the webs thoroughly flexible.

The webs pass from the grooved-rolls, 30,

between the padded rolls, 31, whereby they are restored to fiat condition preparatory to being wound around the take-up roll, 32.

By properly regulating the supply of powder and the supply of moisture, we are able to supply the proper amount of adhesive powder accompanied by' moisture in such limited quantities as to 'cause fibres of one web to directlyl adhere t0 substantially eopposte fibres of the other web independnicety the limited ently of the surrounding fibres in said webs; and also to adherently unite the webs without penetration of the adhesive to the outer surface fibres of either web, so that with most fabrics the grooved-rolls, 30, will be found unnecessary as there will be no substantial areas of hardened adhesive between the webs to be broken up by said groovedrolls.

For certain purposes of the invention therefore, said grooved-rolls are immaterial.

In carrying out our labove described process or method of adherently uniting a plurality of websof fabric, we do not wish to be limited to the use of the particular form of apparatus shown in the drawings, nor to any particular form of apparatus in carrying out said method, as an active adhesive substance, or a dry adhesive substance and a separate supply of moisture, can be applied in any known manner and by the use of any known apparatus, such that a proper quantity of adhesive material is apadhere directly to substantially opposite fibres of the other web independently of the surrounding fibres im said webs and without penetration of the adhesive toy the outer surface-fibres of the webs.

The rolls, 3 and 4, are shielded lby aprons or guards, 78, placed in front of the rolls to intercept any of the adhesive powder or moisture whichmight escape past the-webs. In Fig. 1 the webs in their passage through the machine are indicated by broken lines.

In applying the adhesive substance accoms panied by moisture to the webs by means of an air-blast in the preferredmanner albove particularly described, the adhesive substance and the moisture are applied to the webs 'solely by their own momentum, thus making it possible to re late with lgreat quantities applied to the web-surfaces.

What we claim as new and desire to secureby Letters Patent is- 1. That improvement in the art of adherently uniting a plurality of webs of fabric which consists in pressing said webs together after having interposed between neighborlso,

ot adhesive powder, and atomized vmoisture sulticient to render said powder adhesive.
